Features that make Bolt an awesome CMS

Twig templates

Bolt uses Twig for its templates: an elegant, flexible and concise templating language that allows you to write templates the way you want. You don't have to know PHP or know how databases work in order to get whatever content you need from the backend.

Responsive / Mobile

Bolt's backend interface is fully responsive, so it works on desktop computers, laptops, tablets and phones alike. Very convenient, either on the road or on the couch.

Powerful ContentTypes

The flexible ContentTypes allow you to use all kinds of different fields to create different types of content: pages, blog entries, events, book reviews, or whatever you can think of … all in editable YML files.

Free!

Bolt is completely free to use for both personal and commercial websites. And we're not going to charge you for "premium" features either. Nope, completely free. And did we mention that Bolt is Open Source as well?

PHP 5.5.9 and higher

Bolt requires PHP 5.5.9 and is fully PHP 7 compatible. It requires only some very common modules to be installed. It runs on different types of database engines, and it can be installed on basically any web server.
